The DI Series feature Definitive Technology's most advanced technologies such as BDSS drivers and pivoting Pure Aluminum dome tweeters for spectacular audio performance far beyond traditional flush-mount speakers. Definitive’s exclusive Balanced Dual Surround System (BDSS) driver technology permits these new flush mounts to deliver more bass output and dynamic range than larger drivers. For example, the 4-1/2" driver-based model has the bass and dynamics of a 5-1/4" traditional speaker, while the 5-1/4" performs like a traditional 6-1/2". Pure Aluminum dome tweeter featuring a specially shaped housing that avoids the diffraction distortions of traditional post mounted tweeters, and a sophisticated adjustable crossover network, the DI Series delivers the kind of lifelike sonic performance and broad even dispersion that you've come to expect from Definitive Technology.

I have a full set of Definitive bi-directional speakers to go with this center channel model. I also have a Definitive sub-woofer to compliment the suite of sound paired with a Denon receiver and high-end television. We enjoy our movies! This speaker is a replacement for one we lost due to lightning, so I can definitely say, this is the way to go. Pure sound, great clarity and when I re-connect with 12-gauge Monoprice cables, I expect superb quality output. The in-wall feature means you don't have bulky boxes in the viewing area to navigate and gives a clean look to the room. They sound great, and nobody knows their even there...until you turn up the volume! Then, they rock the house.
